COBRA5485

Get computing speed, rapidly!

COBRA5485 is a credit card-sized Embedded Processor Module based on the Freescale ColdFire MCF5485. The acronym COBRA stands for ColdFire Board for Rapid Applications.

The module can be used for a wide range of applications, especially for tasks requiring high computing performance.

The ColdFire processor family is the successor of the legendary Freescale (formerly: Motorola) 68000 series and was optimized especially for Embedded Applications. It provides high arithmetic performance at low current consumption. Today, several ColdFire processor derivatives are available; the MCF5485 is one of the most recent additions. It delivers more than 300 MIPS (Million Instructions Per Second), contains a Floating Point Unit (FPU), a Memory Management Unit (MMU) and a large variety of interfaces.

The COBRA5485 module contains not only a high-end processor but also a complete set of peripheral functions. The large on-board memory enables the use of powerful operating systems like Embedded Linux.

Software Development for ColdFire

Just like for the 68000 series, a large number of development tools are available for the ColdFire processors, both freeware and commercial offerings. The widespread GNU tool chain (C, C++ and debugger) supports the ColdFire processors as well. It is available for a number of platforms, including Windows-based PCs.

dBug Monitor

dBug is a traditional ROM monitor/debugger that offers a comfortable and intuitive command line interface that can be used to download and execute code. It contains all the primary features needed in a debugger to create a useful debugging environment, such as edit and display memory, line assembler, disassembler, break points and single step operation. dBug is a resident firmware package for the ColdFire family single board computers. The firmware provides a self-contained programming and operating environment. dBug interacts with the user through pre-defined commands that are entered via the terminal.

The COBRA Starter Kit

The Starter Kit contains:

• one COBRA5485 module with dBug Monitor software (pre-installed)
• Carrier Board with sockets for the COBRA module (features see description in right column)
• CD-ROM with development tools (GNU Compiler and Debugger for Windows-Host)
• Documentation incl. Quick-Start-Guide on CD-ROM

Linux

The new MCF5485 processor contains a Memory Management Unit. With this prerequisite, the processor is capable of running a real Linux operating system with full kernel functionality. We help COBRA5485 users to quickly start with Linux development by offering a special Linux distribution, which contains full support for our COBRA5485 board. Using Linux as an operating system, a number of complex functions can be implemented on the COBRA5485 module easily, e.g.:

• File System Management
• Graphical User Interface
• Connectivity (Ethernet)
• Embedded Internet

Linux for the COBRA5485 can be obtained as an optional software package including a complete Linux tool chain and additional documentation. As development environment we recommend a PC with Linux operating system.
